Understanding conversion formulas helps verify calculations and perform manual conversions when needed. The Celsius to Fahrenheit formula multiplies Celsius by 9/5 then adds 32: °F = (°C × 9/5) + 32. Fahrenheit to Celsius reverses this: °C = (°F - 32) × 5/9.
Celsius and Kelvin Conversion: Converting Celsius to Kelvin requires adding 273.15 to the Celsius value. Kelvin represents absolute temperature where 0K equals absolute zero, the theoretical point where molecular motion stops.
Fahrenheit and Rankine Conversion: Rankine relates to Fahrenheit as Kelvin relates to Celsius. Add 459.67 to Fahrenheit to get Rankine. This scale appears in American engineering thermodynamics and power unit conversion calculations.
Quick Mental Conversion: For rough Fahrenheit to Celsius estimates, subtract 30 and divide by 2. This approximation works reasonably well for common weather temperatures.
Memorizing key reference temperatures helps estimate conversions quickly. Water freezes at 0°C (32°F, 273.15K) and boils at 100°C (212°F, 373.15K) at standard atmospheric pressure. Normal human body temperature measures approximately 37°C (98.6°F). Room temperature typically ranges from 20-22°C (68-72°F).
Extreme Temperatures: Absolute zero equals -273.15°C (-459.67°F, 0K, 0°R), representing the coldest possible temperature. The surface of the Sun reaches approximately 5,500°C (9,932°F), while liquid nitrogen boils at -196°C (-320.8°F). These reference points assist with torque calculations in material science applications.
